The JavaScript UI Language (JUL) is a configuration and instantiation module for the JavaScript frameworks. It can be used with any framework that accepts a configuration object as a constructor parameter, or with a custom factory for the other frameworks. It parses a tree of configuration objects and creates the run-time components in the expected order and membership. For most uses, after this step, you will have your application's user interface up and running. It implements programming by configuration for event-driven UI JavaScript frameworks; top-down and bottom-up creation of the component tree; and conversion of a DOM XML document into a configuration tree. It supports configuration inheritance and tparser meta-information inside a configuration node. It has fully configurable parsing and the ability to map node IDs as component instances. It supports serialization of the configuration tree to JavaScript or JSON source code.

file2password is a utility that allows you to select a file (picture, document, music, etc.) and generate a secure password based on it. This means that there is no need to remember any password - just a picture or a filename. It is small (2 KB plus CSS), highly secure as it does not upload or shows the file used, supports drag and drop, can use online storage, and requires no server-side scripting.

SIM.JS is a general-purpose Discrete Event Simulation library fully capable of running in a Web browser. It provides constructs for creating Entities which are the active actors in a system, and encapsulates the state and logic of a system's components. Entities contend for resources, which can be Facilities (supports FIFO, LIFO with preemption and Processor Sharing service disciplines), Buffers, and Stores. Entities communicate by waiting on Events or by sending Messages. Statistics recording and analysis is provided by Data Series Statistics, Time Series Statistics, and Population Statistics. A random number library generates seeded random variates from various distributions, including uniform, exponential, normal, gamma, Pareto, and others.

Lithium is a lightweight library to be used along with jQuery. It takes care of software patterns like classical inheritance, observable (publisher-subscriber pattern), bind, namespace, IE8 JS 1.6,1.8 polyfills, and more, while jQuery takes care of the DOM.

BoardJS is a JavaScript library that simplifies the way of making interactive presentations, stories, and ads. The library works by writing commands such as adding text and images, moving objects, and showing tooltips; once the .go() function is called, commands will be executed one by one. The list of commands will be interpreted in the library as a timeline. It is optimized and fast, is cross-browser and cross-platform, changes the presentation without refreshing the page, applies commands to more than one object at a time, makes it easy to update presentations, uses only HTML, JavaScript, and CSS, and allows multiple shows in the same page.

taccGL is a JavaScript canvas library for animating HTML elements and 3D objects as integrated scenes with depth buffering and shadows. It uses the GPU-accelerated HTML5 canvas (WebGL).
Features include accelerated motion in 2D and 3D space, rotating, mapping of HTML elements on 3D objects, custom shaders, etc. The library loads 3D models from OBJ files.
In WebGL mode, animations mostly run inside the GPU.
Otherwise, there is a restricted fallback to the 2D canvas.
